stat x86-64bi-linux-adventerprise-ms.154-2.s.bin

Do not run ./x86-64bi-linux-adventerprise-ms.154-2.s.bin. Even with strace or in a VM, a well-designed payload can detect sandboxes. Isolate the system from the network if possible.

The version number 154-2 corresponds to IOS-XE Release 15.4(2)S, codenamed Denali.

The file x86-64bi-linux-adventerprise-ms.154-2.s.bin is not a standard Linux binary. It exhibits all hallmarks of: x86-64bi-linux-adventerprise-ms.154-2.s.bin

Recommendation: Do not execute. Do not trust. Quarantine, hash, and submit to antivirus vendors. If found on a production server, assume compromise and rotate all secrets, reinstall from known-good backups, and conduct a full forensic audit.

If you arrived here by searching for this specific filename because it crashed your system or triggered an alert, please contact your security team immediately. For technical analysis of the binary itself (opcodes, syscalls, C2 behavior), a separate reverse-engineering report would be required.

If you discover a file with this name on your Linux system, follow this forensic protocol.

  • Make file non-executable and examine metadata:

  • Run in a safe environment if execution is required:

  • Monitor system calls with strace and file changes with inotify or filesystem snapshots.

  • Extract without executing (if it's a self-extracting shell archive): Do not run

  • Check for digital signatures:

    • pacman -Qo x86-64bi-linux-adventerprise-ms.154-2.s.bin

    If the output is no package found, the file is an orphan – a strong indicator of compromise.
